The QPF4506B from Qorvo is a Wi-Fi 6 Front-End Module that operates from 5150 to 5850 MHz. It has been designed for Wi-Fi 802.11ax systems and offers a compact form factor with integrated matching that minimizes layout area in the application. This module consists of a 5 GHz power amplifier (PA), bypassable low noise amplifier (LNA), regulator, single pole double throw (SP2T) switch, logarithmic power detector, and a coupler. It optimizes the performance of the PA to conserve power while maintaining the highest linear output power and excellent throughput.
On the Tx side, this front-end module delivers an output power of 20 dBm with a gain of 30 dB. On the Rx side, it provides a gain of 14 dB with a noise figure of 1.9 dB. This module integrates die-level filtering for second and third harmonics along with 2.4 GHz rejection for DBDC operation. It requires a DC supply of 5 V and consumes 36 mA of current in Rx mode. This RoHS-compliant RF module is available in a laminated package that measures 3 x 3 mm and is ideal for use in access points, customer premise equipment, residential gateways, wireless routers, and IoT applications.
